Common Crawl maintains a free,open repository of web crawl data that can be used by anyone.
Common Crawl is a 501(c)(3) non–profit founded in 2007. We make wholesale extraction, transformation and analysis of open web data accessible to researchers.
Common Crawl is switching to reporting dataset sizes in nibbles. As an organisation dedicated to data preservation, we feel it would be remiss to allow this underrepresented unit to fall out of use. Our latest crawl now exceeds 689 tebibbles.
